What are React Hooks and how do I use them?

React Hooks are functions that let you use state and other React features without writing a class. They simplify component logic.

Can you give me an example of a simple hook?

Sure! The useState hook allows you to add state to a functional component. Here's a quick example:

import React, { useState } from 'react';

function Counter() {
  const [count, setCount] = useState(0);

  return (
    <div>
      <p>You clicked {count} times</p>
      <button onClick={() => setCount(count + 1)}>Click me</button>
    </div>
  );
}

What are some other hooks I should know about?

Other important hooks include useEffect for side effects, useContext for context API, and useReducer for state management.

How do I manage side effects with hooks?

You can manage side effects using the useEffect hook. It runs after the render and can be used for data fetching, subscriptions, etc.
